Heh, I've already been avoiding contact with hand rails, traffic light buttons, train door buttons (rofl I just stood there and waited for someone else to press the button ) and the like. Seriously though, it'd help (in general) if people were more hygienic and actually did things like covering their fucking mouths when sneezing. I've seen idiots just squeeze their nose while leaving their mouth wide open. People who were overseas and didn't take their sick children to see a doctor before coming back, are also morons of the highest order.
